Alstroemeria plant named ‘Tesrobin’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Tesrobin’, characterized by its compact and mounding plant habit; sturdy and strong plants; vigorous growth habit; intense red-colored flowers; and good garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Tesrobin’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofAlstroemeria plant, botanically known as Alstroemeria hybrida, growntypically as a potted garden Alstroemeria, and hereinafter referred toby the name ‘Tesrobin’.

The new Alstroemeria is a product of a planned breeding programconducted by the Inventor in De Kwakel, The Netherlands. The objectiveof the breeding program is to create new potted garden Alstroemeriacultivars that flower continuously and have attractive foliage andflower coloration.

The new Alstroemeria originated from a cross-pollination made by theInventor in De Kwakel, The Netherlands in May, 2003, of a proprietaryAlstroemeria hybrida selection identified as code number E607, notpatented, as the female, or seed, parent with a proprietary Alstroemeriahybrida selection identified as code number ZB4061A, not patented, asthe male, or pollen, parent. The cultivar Tesrobin was discovered andselected by the Inventor as a flowering plant from within the progeny ofthe stated cross-pollination in a controlled environment in De Kwakel,The Netherlands in May, 2004.

Asexual reproduction of the new Alstroemeria by root divisions in acontrolled environment in De Kwakel, The Netherlands since the fall of2004, has shown that the unique features of this new Alstroemeria arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Tesrobin has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Tesrobin’. These characteristics incombination distinguish ‘Tesrobin’ as a new and distinct cultivar ofAlstroemeria:

-   -   1. Compact and mounding plant habit.    -   2. Sturdy and strong plants; vigorous growth habit.    -   3. Intense red-colored flowers.    -   4. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the parentselections. Plants of the new Alstroemeria differ from plants of theparent selections primarily in flower color as plants of the parentselections have pink-colored flowers.

Plants of the new Alstroemeria can be compared to plants of theAlstroemeria hybrida cultivar Staprivane, disclosed in U.S. Plant Pat.No. 14,131. Plants of the new Alstroemeria differ primarily from plantsof the cultivar Staprivane in flower color as plants of the cultivarStaprivane have purple-colored flowers. In addition, plants of the newAlstroemeria have shorter peduncles than plants of the cultivarStaprivane.

Plants of the new Alstroemeria can also be compared to plants of theAlstroemeria hybrida cultivar Staprioxa, disclosed in U.S. Plant Pat.No. 14,075. Plants of the new Alstroemeria differ primarily from plantsof the cultivar Staprioxa in flower color as plants of the cultivarStaprioxa have red purple and yellow-colored flowers. In addition,plants of the new Alstroemeria have shorter and stronger peduncles thanplants of the cultivar Staprioxa.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Alstroemeria, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Alstroemeria. The photograph comprises a side perspective viewof a typical flowering plant of ‘Tesrobin’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants of the new Alstroemeria grown in De Kwakel,The Netherlands during the winter in a glass-covered greenhouse incontainers. During the production of the plants, day temperaturesaveraged 20° C. and night temperatures averaged 14° C. Plants used forthe photograph and description were about ten weeks from planting.
